Abstract: The present disclosure provides a method and system for altering the drag force on a wind capturing structure. First, the present disclosure implements a new bridle system. Mainline 70 attaches to the bridle of kite 72, which consists of two bridle lines 74 and 76 joined at single point 78 at the top of the kite, and two separate points 80 and 82 at either side of the bottom of the kite. Mainline 70 wraps around the two bridle lines with sliding mechanism 84; sliding mechanism 84 may be able to slide up and down the bridle lines 74 and 76 like a bolo. The present disclosure also presents unpowered, automatic, and powered sliding mechanisms which may alter the lift and drag forces on the wind capturing structure.

Abstract: A system for harnessing power from wind using a wind capturing structure. An axis of rotation could be central to the system, and the lines could rotate around this axis. Features for the wind capturing structure include effective downwind power generation using a durable, lightweight, inexpensive structure that may be safe in the event of a crash, and easily modified to reduce drag for retraction. The capturing structure creates lift in a low altitude environment, capable of operating in high wind conditions. The lines include minimal mass to permit lift at low altitudes, and are constructed with maximum tensile strength to prevent failure in high winds. A versatile wind capturing structure could include a kite operable in variable conditions for efficient and consistent production of force. The power producing cycle of a system capturing power from wind should maximize the efficiency of the system.
